What are Longhorn stuffed mushrooms made of?

They're made with white button mushrooms stuffed with a blend of garlic herb cheese , white cheddar , and Alfredo sauce , then topped with Parmesan cheese and breadcrumbs before being baked until golden.

What kind of cheese is used in Longhorn stuffed mushrooms?

The star of the filling is white cheddar cheese , often mixed with cream cheese or garlic herb cheese spread . The topping typically includes Parmesan for that crisp, golden finish.

Can I make them ahead of time?

Yes! You can prep the mushrooms a day in advance , stuff them, and keep them covered in the fridge. Just wait to bake them until just before serving for the best texture.

What’s the sauce under Longhorn’s mushrooms?

That’s Alfredo sauce ! It adds richness and moisture to the base, and complements the garlic and cheese flavors perfectly. You can use a quality store-bought brand or make your own.

Can I freeze stuffed mushrooms?

Technically yes, but it's not ideal due to the dairy-based filling. If needed, freeze them before baking and avoid adding Alfredo sauce. Bake directly from frozen, adding extra time.

Can I add meat to the filling?

Absolutely. You can mix in crumbled bacon , shredded chicken , or crab meat for added flavor and protein. Just make sure it's pre-cooked and finely chopped before adding to the filling.
